CHURN.

Specification of LettersPatent N 0. 3,556, dated April 20, 1844;.

Figure 1, is a side elevation; Fig. 2, a-

front elevation; Fig. 3, is the dasher detached.

The driving power of my churn is a weight (w) which is suspended by acord (a?) that passes up over apulley or rollerty) situated at anyheight above it; from them the cord descends to a drum ((Z) around whichit is wound. On the drum shaft a spur wheel is fastened that gears intoa pinion (e) on a shaft below; on this shaft is a wheel (6) that turnsloosely on said shaft; it can be connected with the shaft when turningin one direction by means of a ratchet wheel (6 and pawl (71 in the samemanner as the barrel of a clock. On the same shaft outside the framethere is a pulley (6 around which an endless band (6 passes down to twopulleys (4) below and from thence horizontally forward and around ahorizontal wheel (8) on which the churn rests, and by which it isturned. The pulleys (7") placedside by side, only one of which is shown,can be raised or lowered in any convenient way so as to stop or put inmotion the churn as required. This can be done by attaching the pulleysto a piece (7') that is movable and tightening or slackening the band (6The wheel (6) works into a pinion (f) connected with the same shaft asthe spur wheel (f) that drives a pinion (g) on the balance wheel shaft.The balance wheel (h has a crank pin on one of its arms that is madeadjustable at a greater or less distance from the center. This isconnected with a horizontal working beam (71) by a rod To the other endof the working beam a shackle bar is con nected that hangs down and hasa slot in its lower end of sufficient length through which two boltspass, the lower one being connected with a spring thumb piece (Z)outside so that when thethumb piece is pressed down it draws out thebolt." The handle (70) of the dasher is made to fit the slot and has anotch cut in its upper end; below this slot or notch are two or threeholes (see Fig. 3). When the end of this dasher is slipped into the slotin the shackle the notch embraces the upper shackle and the pin on thespring thumb piece enters one of the holes in the dasher handle whichregulates its length. Thus as the length of the crank is altered that ofthe handle can be adjusted to it and the dash always in its down strokeplay near the bottom of the churn.

At the commencement of the operation the cord or band (6 is slack;byraising pulleys (1") when butter comes the pulleys are brought downand the churn is made although in a manner somewhat different from mine,but

What I claim as my invention and desire V to secure by Letters Patent isThe employment of a revolving churn and reciprocating dash, incombination with the driving power as herein described for making andworking butter.
